The invention relates to a construct for controlling
insect pests and a method thereof. The construct comprises a Cry1Ca
protein and a Cry1A
protein. According to the construct for controlling
insect pests and the method thereof, the
protein Cry1Ca and Cry1Ab / Ac are generated in plants so as to control the
insect pests. Compared with agricultural control methods,
chemical control methods and biological control methods are used in the prior art, the method is high in
toxicity, complete in effect,
pollution-free, residue-free, stable in effect, simple, convenient and economic, and the plants are subjected to whole-growth period and whole-
plant protection so as to prevent intrusion of the insect pests.
